2008 Kia Sedona Used PCM

Programming
2008 Kia Sedona 3.8L (3) 5-spd

Hi all, I diagnosed the transmission issue with this vehicle to be a bad driver for the L/R solenoid.

A new PCM is $2300 CAN so a used one was sourced.

I attempted to do the immobilizer the same way as I have done many Hyundais of the same vintage.

I have never done a KIA, but I figured it would be similar.

I used the PIN from the "new" module to neutralize the PCM, then used the PIN from the vehicle to try to reprogram the keys.

Anyway, nothing worked and I could not get it running. Can this be done on the bench?

Attached is a pic of the module, I don't know how in the hell you would even get it apart.

Any help would be appreciated

Hello there, There is no way currently to program used Hyundai/Kia ECUs You can open it and find a what component might hold vin and immo data and you can clone it......

Hi Todd, The USA models are different as we don't have as many immobilized PCMs with bladed keys. I have not experienced this ECU yet but most of the time you need to clone all portions of the memory both inside the MCU (Microcontroller) and the external EEPROM if present. With the non-immo ECUs, you just have to correct the VIN.

Hi Mike,yes I forgot that USA Hyundai/ Kia vehicles were non immobilizer for the most part. However, I have always been able to make used Hyundai ECM's work using the method I described. I am 0 for 2 on Kia.

Todd, I sent you a message on FB. You may also look at searching some of the dealer sites in US. I believe I saw that ECU online for about $900 USD. I am fairly confident we can find a way to make that one work.

I attempted to program a used BCM on a KIA a few months back. If it's made by Mitsubishit, forget it. They are locked. I ended up replacing a transistor and a relay from the boneyard unit and after the organ transplant to original BCM, the functions were restored. I can't believe that Mitsubishi and others prefer to trash perfectly working units in order to make money at exorbitant prices. It's…
